Hey, thanks for stopping by. I'm Mr. Perez.
2
00:00:04.800 --> 00:00:11.520
Okay, Charlie, let's get to work right there. Find the area and the perimeter of the figure below.
3
00:00:11.520 --> 00:00:17.840
First, let's find the perimeter. Remember, the perimeter is the sum of all the side lengths.
4
00:00:17.840 --> 00:00:22.880
So let's add up our side lengths, Charlie. Remember, we can go in any order. We'll go this way.
5
00:00:22.880 --> 00:00:30.800
16 inches plus 12 inches plus 11 inches plus 13 inches. And when you add them all up,
6
00:00:30.800 --> 00:00:36.560
what'd you get, Charlie? 52 inches. Very nice there, Charlie. Don't forget to circle or box your answer.
7
00:00:37.280 --> 00:00:44.560
Now, let's find the area. We have a trapezoid here. And the equation for the area of the trapezoid
8
00:00:44.560 --> 00:00:51.680
is area equals one-half times the height times the sum of the bases. Well, notice our height
9
00:00:51.680 --> 00:00:57.840
is indicated right here as 12 inches. And let's substitute in our height into our equation,
10
00:00:58.400 --> 00:01:04.320
12 inches. And we'll call base one, 16 inches, and base two, 11 inches.
11
00:01:06.320 --> 00:01:12.400
Now, let's bring down our work. 16 inches plus 11 inches is what, Charlie? 27 inches.
12
00:01:12.400 --> 00:01:21.040
Very nice. And now, half a 12 is six. And what's six times 27, Charlie? 162. Very nice there.
13
00:01:21.040 --> 00:01:26.400
Now, Charlie, what's our dimensions for area in this problem? In two squared. That's right.
14
00:01:26.400 --> 00:01:56.240
Always put your dimensions and don't forget to circle or box your answer. We'll see you all again soon.
